I am developing a software where the users can access any website through the clicking a java button.
JButton button1 = new JButton("Click Me");
button1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent myEvent) {
// Here clicking this method will open a website
open("www.myrequiredWesite.com");
}
});
How can i call default browser from the above java source code so that the default browser will open the specific site clicking the button from java graphical user interface.
public static void openPage(URI uri) {
Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE)) {
try {
desktop.browse(uri);
} catch (Exception e) {
e.printStackTrace();
}
}
}
public static void openPage(URL url) {
try {
openPage(url.toURI());
} catch (URISyntaxException e) {
e.printStackTrace();
}
}
Note use java.net to use desktop object

How do I open a website using a JButton in Java?
You can use the Desktop API#browse to achieve it.
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
openWebpage("http://stackoverflow.com/help/how-to-ask");
}
});
public void openWebpage(URI uri) {
Desktop desktop = Desktop.getDesktop();
try {
desktop.browse(uri);
} catch (Exception e) {
e.printStackTrace();
}
}
I'm trying to implement a JEditorPane with hyperlinks. I'm using a HyperLinkListener but it seems to never trigger.
Code:
JEditorPane editorPane = new JEditorPane("text/html", programInfo);
editorPane.addHyperlinkListener(e -> {
System.out.println("CLICK");
if (e.getEventType().equals(HyperlinkEvent.EventType.ENTERED))
try {
if (Desktop.isDesktopSupported()) {
Desktop.getDesktop().browse(e.getURL().toURI());
}
} catch (IOException e1) {
e1.printStackTrace();
} catch (URISyntaxException e1) {
e1.printStackTrace();
}
});
JOptionPane.showMessageDialog(contentPane, editorPane);
Sample HTML:
<body>
<p><b>Author:</b> James - sample</p>
</body>
This leads to this:
But when I click on the links nothing happens.
Additional Info:
I'm testing this on Ubuntu 14.04.
I have set Look and Feel to system.
EDIT: thanks to #AndrewThompson for finding the real issue.
The reason why it does not trigger events is because the editor pane will only fire events when it is not editable. So, to make your code work you should add this line after the construction of the editorPane:
editorPane.setEditable(false);
Below you can find a self contained example:
public class TestFrame extends JFrame {
public static void main(String[] args) {
JEditorPane editorPane = new JEditorPane("text/html", "test link to example.com");
editorPane.addHyperlinkListener(new HyperlinkListener() {
#Override
public void hyperlinkUpdate(HyperlinkEvent e) {
System.out.println("CLICK");
if (e.getEventType().equals(HyperlinkEvent.EventType.ENTERED)) try {
if (Desktop.isDesktopSupported()) {
Desktop.getDesktop().browse(e.getURL().toURI());
}
}
catch (IOException e1) {
e1.printStackTrace();
}
catch (URISyntaxException e1) {
e1.printStackTrace();
}
}
});
editorPane.setEditable(false); // otherwise ignores hyperlink events!
JFrame frame = new JFrame("EditorPane Example");
frame.add(editorPane);
frame.setSize(300,200);
frame.setVisible(true);
} }
(sorry, I removed the lambda because I don't have a jdk8 on this PC)
I have a set of JButtons, each of which opens a separate YouTube video webpage. When first running the program, I can click on any ONE button and get the video page. When I try to get another video page with a button click, it doesn't work - in fact, all the buttons are deactivated. This is the case whether or not I close the video webpage.
How can I keep all the buttons activated? Thanks in advance.
Here's the code for reference. The button links and tags are populated from a text file.
//import statements
public class VideoRecord extends JFrame {
private File videoRecordFile;
public VideoRecord() throws FileNotFoundException {
setVisible(true);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setLayout(new GridLayout(2,2));
setSize(new Dimension(500, 500));
videoRecordFile = new File("videorecord.txt");
getButtons();
pack();
}
public void getButtons() throws FileNotFoundException {
Scanner input = new Scanner(videoRecordFile);
while (input.hasNextLine()) {
Scanner lineInput = new Scanner(input.nextLine());
while (lineInput.hasNext()) {
final String urlString = lineInput.next();
String buttonText = lineInput.next();
JButton btn = new JButton(buttonText);
add(btn);
btn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
try {
URL videoURL = new URL(urlString);
URLConnection videoConnection = videoURL.openConnection();
videoConnection.connect();
openWebpage(videoURL);
}
catch (MalformedURLException mue) {}
catch (IOException ioe) {}
setEnabled(false);
}
});
}
}
}
public static void openWebpage(URI uri) {
Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE)) {
try {
desktop.browse(uri);
} catch (Exception e) {
e.printStackTrace();
}
}
}
public static void openWebpage(URL url) {
try {
openWebpage(url.toURI());
} catch (URISyntaxException e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws FileNotFoundException {
VideoRecord vr = new VideoRecord();
}
}
Take a second to look at you code...
btn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
try {
URL videoURL = new URL(urlString);
URLConnection videoConnection = videoURL.openConnection();
videoConnection.connect();
openWebpage(videoURL);
}
catch (MalformedURLException mue) {}
catch (IOException ioe) {}
setEnabled(false);
}
});
When you click a button you call setEnabled(false);...
This has actually disable the frame, not the button that was clicked...
Try using ((JButton)e.getSource()).setEnabled(false) instead
Don't throw away you Exceptions blindly, they provide important and useful information that can help solve problems
I made my displayMessage() clickable this way (thanks stackoverflow!):
public class Tray {
private static class ShowMessageListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
trayIcon.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (openBrowser == 1) {
Desktop desktop = Desktop.isDesktopSupported() ? Desktop
.getDesktop() : null;
if (desktop != null
&& desktop.isSupported(Desktop.Action.BROWSE)) {
try {
desktop.browse(URI.create(link));
} catch (Exception e2) {
LogError.get(e2);
}
}
}
openBrowser = 0;
}
});
trayIcon.displayMessage("Finished", link,
TrayIcon.MessageType.INFO);
}
} //ShowMessageListener class end
invisibleItem.addActionListener(new ShowMessageListener());
}
and I'm dispatching event to show the message:
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(new ActionEvent(Tray.invisibleItem, ActionEvent.ACTION_PERFORMED, "asd", 1, 0));
Everything works great, the message is clickable. It was perfect until I realized that ActionListener is listening to TrayIcon too. If the user doesn't click on the message, TrayIcon will take the event on the next click and open the website.
Here's my question: how can I check if displayMessage() is gone?
